Well, there are some answers already. But... For security reason I made the way around, Instead of using the standard core pointer, I do configure explicitly the input devices I use. I made this to prevent a malicious USB device plugged in that exploits some flaws or could act as a key logger. I would like to have a whitelist or to enable the devices manually. The bad side of this setup are: - I could not plug additional devices like a barcode reader or a wacom tablet - All devices must be present at X server start. I found a way to redetect a device that was plugged out and in again with xinput disabling and reenabling it (like a bluetooth mouse) but I found no way to manually add new devices by intention. If it is not working automated, it doesn't work at all. But this is not specially related to fvwm than to X itself.

Nope, runs as me at login in my X session. You could probably make it a systemd user unit with six years of research :-). I just run it as a startup program in my session.

I'm reluctant to push these to system settings, as they're personal onces I should be able to move around in my $HOME folder (and in my previous employer I could not even have adjusted this configuration) -- but I can see what you are saying. I suppose I'd need to work out the equivalent of xmodmap in these Xkb* settings, as well as the other settings: xmodmap ~/.xmodmap # custom layout xset r rate 300 100# keyboard repeat xset m 0.4 # mouse acceleration xsetwacom --set "Wacom One by Wacom M Pen stylus" MapToOutput DisplayPort-0 The X server could really be more helpful here: "xset r" is presented as a global setting, yet it sets the current keyboards, not newly added ones. Same for "xset m" with mice. What do fvwm users do if they have a custom keyboard layout? -- Mark

As example, I have nothing special for the USB mouse, it just work, and for the keyboard I have a file /etc/X11/xorg.conf.d/30-keyboard.conf Section "InputClass" Identifier "evdev keyboard catchall" MatchIsKeyboard "on" MatchDevicePath "/dev/input/event*" Driver "evdev" Option "XkbLayout" "ch" Option "XkbVariant" "fr" Option "XkbRules" "xorg" EndSection Dominique

You could check out the silly program I wrote to handle this exact situation. It listens for udev events. https://tomhorsley.com/software/udev-act/udev-act.html
